Adorna Free product w/ shipping charge. Charged 89.99 a week after recieving product Internet

 I came across a product from Adorna that was free. All I had to do wad pay about $3 in shipping, and that was it. It wasn't a trial or anything that should have kept and charged my card for anything else. Now, a week and a half later, I just got charged an insane amount of $89.99 from them for no reason at all, which has also caused me to go into the negative. Wonderful time for the holidays. I looked online and found an incredible amount of reports of this happening to literally everyone who has gotten their "free" product, and I don't know what to do. There is no way I'm letting this go. I've tried calling, and gotten no one to answer or call me back.
